更新时间:2024.05.24     作者:管理员      浏览次数:2

General-purpose plastics are those varieties of plastics that are produced in large quantities, are inexpensive, have a wide range of uses, and have a wide range of influences. These plastics usually have excellent physical and chemical properties and can be moulded and processed by various processing methods. The following are some common general-purpose plastics:

1. Polyethylene (PE): Polyethylene is the most productive variety in the plastics industry, with excellent low temperature resistance, electrical insulation and chemical stability. According to the different densities, polyethylene can be divided into low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE).

2. Polypropylene (PP): Polypropylene is a thermoplastic with excellent resistance to cooking, corrosion and strength. Polypropylene is widely used because of its low price, good overall performance and easy processing.

3. Polyvinyl Chloride (PVC): PVC is a plastic obtained through the polymerisation of vinyl chloride, the hardness of which can be changed by adding plasticisers. hard and soft products made of PVC have a wide range of uses, such as wires and cables, building materials, medical equipment.

4. Polystyrene (PS): Polystyrene is a colourless and transparent thermoplastic with excellent transparency, processability and decorative properties. Polystyrene is commonly used to make various packaging materials, containers, toys and so on.

5. Acrylonitrile-butadiene-styrene copolymer (ABS): ABS is a thermoplastic polymer structure material with high strength, good toughness, easy processing and moulding, and it has excellent comprehensive performance.ABS is widely used in automobiles, electronic and electrical appliances, instrumentation, textiles and construction and other industrial fields.


In addition to these common general-purpose plastics, there are some other varieties of general-purpose plastics, such as polymethyl methacrylate (PMMA), polyoxymethylene (POM) and so on. These plastic varieties have a wide range of applications in their respective fields.
